Spam related cyber crimes have become a serious threat to society. Current spam research mainly aims to detect spam more effectively. We believe the identification and disruption of the supporting infrastructure used by spammers is a more effective way of stopping spam than filtering. The termination of spam hosts will greatly reduce the profit a spammer can generate and thwart his ability to s...

Computer hackers or their malware surrogates constantly look for software vulnerabilities in the cyberspace to perform various online crimes, such as identity theft, cyber espionage, and denial of service attacks. It is thus crucial to assess accurately the likelihood that a software can be exploited before it is put into practical use. In this work, we propose a cognitive framework that uses B...
